Approaches of output improvement for a cesium vapor laser pumped by a volume-Bragg-grating coupled laser-diode-array

We report the approaches of output improvement for a cesium vapor laser, which was pumped by a volume-Bragg-grating (VBG) coupled broad-area laser-diode-array (LDA) with the quasi-continuous-wave (QCW) drive mode, in adopting an appropriate heating procedure and improving the pump configuration.
